Q: What is the Connection Between Tremors & Anxiety?

A:  (Pay attention how close this plays in the endocrine system. -mgf)

Tremors are repeating, involuntary muscle contractions that appear as shaking or trembling. This shaking may affect a single area, such as the hands, or may be generalized over the whole body. Tremors and anxiety are frequently linked, thanks to the unique set of physiological reactions that occur when a person is suffering anxiety.
When a person is experiencing anxiety, fear, or stress, the body gears up to deal with a potential threat. This is sometimes called the “fight or flight” reaction, and it may occur far more often and with more strength in some people than others. While anxious, the body may release a flood of chemicals, including epinephrine. This hormone, which comes from the adrenal glands, boosts oxygen levels, increases heart rate and blood pressure, and may cause the connection between tremors and anxiety when it is released in high levels.

  1. Hi...=)
    it might be interesting if u can teach us how to detect fine tremors...
    and how to differentiate tremors from anxiety and those from hyperthyroidism.

  2. Sorry for the delay in answering your question, I didn't receive a notice from Blogger! :/

    To answer your question...

    Well, the thing about that is tremors are a physiological symptom. So many different things can cause tremors as you can see above...anxiety and what you mentioned hyperthyroidism. Both of these can cause postural tremors...and both have to do with the release of hormones. And for anxiety, its one of those reciprocal type of activity...where one may get fine tremors ...and due to learned experiences of past anxiety can become more anxious just by the feeling of the tremors.

    If you are trying to find out if an individual has hyperthyroidism... then it's best for a doctor to run test to see what type of a tremor it may be and the underline cause of it.

    But all in all, if you have hyperthyroidism and you are trying to detect if the tremor is coming from anxiety, you would have to identify other symptoms at that point...are you worrying about something? are you under a lot of stress at that moment? etc.

    And side note: there are different types of tremors (postural,resting, intention, essential, etc.) but for anxiety and hyperthyroidism they fall under the same subtype: postural tremors.

    I hope that answered your question if not...let me know :)
